Aurora Forecast Update for 2025-10-02T10:50:04Z

ALERT: Geomagnetic K-index of 5
Threshold Reached: 2025 Oct 02 1038 UTC
Synoptic Period: 0900-1200 UTC

Active Warning: Yes
NOAA Scale: G1 - Minor
Additional Details Here.

Space Weather Message Code: ALTK05
Serial Number: 1874
Issue Time: 2025 Oct 02 1045 UTC

ALERT: Geomagnetic K-index of 5
Threshold Reached: 2025 Oct 02 1038 UTC
Synoptic Period: 0900-1200 UTC

Active Warning: Yes
NOAA Scale: G1 - Minor

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/noaa-scales-explanation

Potential Impacts: Area of impact primarily poleward of 60 degrees Geomagnetic Latitude.
Induced Currents - Weak power grid fluctuations can occur.
Spacecraft - Minor impact on satellite operations possible.
Aurora - Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.

A. NOAA Geomagnetic Activity Observation and Forecast

The greatest observed 3 hr Kp over the past 24 hours was 6 (NOAA Scale
G2).
The greatest expected 3 hr Kp for Oct 02-Oct 04 2025 is 5.67 (NOAA Scale
G2).

NOAA Kp index breakdown Oct 02-Oct 04 2025

Oct 02 Oct 03 Oct 04
00-03UT 5.33 (G1) 4.00 0.00
03-06UT 5.00 (G1) 4.00 0.00
06-09UT 5.00 (G1) 3.33 0.00
09-12UT 5.67 (G2) 3.67 0.00

18-21UT 4.33 4.00 0.00
21-00UT 3.67 3.33 0.67

Rationale: G1-G2 (Minor-Moderate) geomagnetic storms are likely on 02
Oct due to CH HSS influences.

B. NOAA Solar Radiation Activity Observation and Forecast

Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was
below S-scale storm level thresholds.

Solar Radiation Storm Forecast for Oct 02-Oct 04 2025

Oct 02 Oct 03 Oct 04
S1 or greater 5% 5% 5%

Rationale: No S1 (Minor) or greater solar radiation storms are expected.
No significant active region activity favorable for radiation storm
production is forecast.

C. NOAA Radio Blackout Activity and Forecast

Radio blackouts reaching the R1 levels were observed over the past 24
hours. The largest was at Oct 01 2025 0226 UTC.

Radio Blackout Forecast for Oct 02-Oct 04 2025

Oct 02 Oct 03 Oct 04
R1-R2 60% 60% 60%
R3 or greater 15% 15% 15%

Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely with slight
chances for isolated R3 stronger events all three days.
